CS51414ED8G

Overview

The CS51414ED8G is a step-down switching regulator IC manufactured by onsemi. It operates as a buck converter with an adjustable positive output voltage ranging from 1.27V to 38V. The device supports a maximum output current of 1.5A and utilizes V2 control architecture for stable regulation. It functions at a fixed switching frequency of 520 kHz, distinguishing it from the 260 kHz variants in the CS5141X family. The input voltage range spans from 4.5V to 40V. The component is housed in an 8-SOIC package (0.154 inch width) and is designed for surface mount installation.

Feature Summary

Implements V2 control architecture for transient response optimization
Provides adjustable output voltage capability within specified limits
Integrates synchronous rectification for improved efficiency

Applications

Point-of-load regulation in industrial equipment
Power supply stages for embedded systems
Voltage conversion for communication infrastructure

Procurement Notes

Verify component status carefully as this part is listed as obsolete or end-of-life by major distributors. Confirm availability of equivalent alternatives such as the CS51414EDR8G if current production is required. Ensure that any substitute maintains the same SOIC-8 footprint and electrical specifications to guarantee compatibility with existing designs without modification.

Selection Notes

Select this component when a 520 kHz switching frequency is required for smaller passive component sizes compared to 260 kHz alternatives. The 1.5A current rating suits moderate power applications. Verify that the input voltage does not exceed 40V and that the thermal performance of the SOIC-8 package meets the system's heat dissipation requirements under full load conditions.

Part Context

This device belongs to the CS5141X series of 1.5 A buck regulators from onsemi. The series includes variants operating at different frequencies, specifically 260 kHz and 520 kHz. The CS51414ED8G represents the 520 kHz option within this family, offering faster transient response characteristics due to the higher switching speed while maintaining the core V2 control features found across the series.
